Specification of Letters Patent. Patented Aug. 15), 1929.

Application filed. February 28, 1919. Serial No. 279,839.

To all whom it may concern:

Be it known that I, ALEXANDER T. FISCHER, citizen of the United States, residing at Detroit, county of l/Vayne, State of Michigan, have invented a certain new and useful Improvement in Apparatus for Deflecting Fire of Firearms, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has forits object the construction of a multiple deflecting device for fire arms arranged in a carrier so that a cone of fire may be directed in any desired direction or angle of elevation and at the same time shelter theoperators from hostile fire and it consists in .the construction and arrangement hereinafter described and claimed.

In the drawings: T

on the carrier.

In Fig. 1 numeral 1 designates the carrier made in the form of a tank container with inlet 2 and outlet 3. 4 is. an upright stand ard two of which are provided as indicated in Fig. 2. The carrier issup'ported between said standards by trunnions 5 by means of which said carrier is permitted to tilt from itsnormal horizontal position, said tilting being regulated by means of gears 6 and 7, regulated by escapement 8, which is in turn controlled by a spring 9 and lever 10' is adapted to operate the gears and escapement, or the movement may initiate with the escapement by means of escapement lever 11.

4 and 4 are braces for upright standard 4. Rotatable platform 22 which carries the device is supported upon a bearing plate 12 which carries a multiplicity of balls 13 and is in itself superimposed upon a stationary platform 14. Said rotatable table is further provided with hand screws 15 providedat theirlower extremities with frictional bearing plates 16 to establish a frictional contact with thestationary platform 14 and thus prevent the device from rotating when said screws are fastened down. 17 and 18 respectively are forward and rearward chainsfor maintaining the desired elevation of the device. 18? is a hook forreceiving the links of said chain 18 and at tached to the table 22, 19 being a turnbuckle for tightening the forward chain. 20 is a cover plate shown here as bolted or screwed to the carrier 1. 21 isthe projecting end of the deflecting-devices; Y

Fig.2 is a top plan view of .the'device as in 1 and is self explanatory.

' Fig. 3 is a vertical sectional view of the device showing the firearm 23 .telescoped the carrier proper and. constituting the means of support for the deflecting devices. Covering plate 20 is. shown fastened down A cross sectionof the bearing 12 and the ball bearings 18 is likewise shown, also the central support shaft 24 and the rotatable table 22. Perforations of the end castings1 which do not extend all the way through but rather in a honey-comb like manner are shown in longitudinal section at 25.

Fig. 4 is a vertical cross section-of one of ion the end castings taken onthe line 4c' :i: of Fig. 3. The view is self explanatory. It shows the opening 21 in the end casting through which the deflecting devices protrude, and the honey-combed perforations 25 before mentioned, which form that part of the circulatory water cooling system which is used to cool the end castings.

Fig. 5 is a fragmentary sectional view of the forward and rearward castings vertically through one of the deflecting devices 21 and showing a modification of the method of inserting the firearm in the device. In this view the firearm 23 is shown as threaded on its outer surface and screwed into the device.

Fig. 6 is a fragmentary vertical sectional view through'one of the deflecting devices of the rearward casting, which shows another method of inserting the firearm as distinguished from the methods shown in Figs. 3 and-5. In this instance it is accomplished by means ofa joining member 26 provided with set screws 26 and 26". The deflecting device 21 in this instance must project beyond the end of the rearward casting, and the joining member 26 is then fastened by means of the set screws 26 and 26 to the rearward projecting end of said deflecting device and the muzzle of the rifle as illustrated.

F i 7 is a vertical sectional view taken through one of the hand screws 15, project ing through the rotatable table 22 showing the frictional bearing plate 16, and the method of applying the friction to the lower stationary platform 14.

F ig. 8 is a vertical sectional view through the axes of the gears. 5 is the trunnion on which the device operates, 6 and 7 are the gears respectively, '10 the hand lever shown modification shown in Fig. 9 showing two tiers of vertically arranged deflecting de-' vices, the curvature being downward as shown in Fig. 9, and it is thought this view is easily understood as Fig. 9.

Fig. 11 is a cross sectional view taken on the line 1111 of Fig. 9 through two. of the deflecting devices 21 and through the barrels of inserted firearms 23. Method of inserting by means of a joining member 26 as shown in. Fig. 6 and hereinbefore described, is here illustrated.

5 with its operating gears 6 and 7, regulated by escapeinent S or by means of the hand lever 10 provides means for obtaining the desired angle of elevation, the device being retained at the angle thus obtained-by means of chains 17 and 1 8, the desired length of chain 18 being regulated by means of a hook 18 attached to the rotatable table and adapted to grasp a link in the said chain, the

tension of the forward chain is more carefully regulated by means of a turn-buckle 19. The desired shape of the cone of fire may be secured by turning the individual deflecting devices in the carrier so that the curvature will be in such a direction as to produce the desired result. 7

The carrier is made in the form of a water tank, with inlet port 2 and. outlet port 3 to. provide water circulation therein,

and the end castings are honey-combed so as to provide a circulatory. cooling system for the end castings.

The device is particularly adapted. for use with shotguns. It is realized that rifling of the deflecting device is impracticable. By virtue of the curvature there will of necessity be an escape of the propulsive gas and consequent lessening of the velocity and shortening 'of the effective range. Used with smooth bore firearms however, which throw a number of projectiles at one discharge at a short range, the device provides a means for controlling the cone of fire as to density and direction. 7 A

It is furthermore apparent from the description that the device if used behind protected earthworks would permit the user to remain entirely concealed behind such works during its operation.

Having thus described my invention what I claim is:

1. In a device of the class described, a gun platform, a rotatable table mounted thereon, friction plates carried by said rotatable table adapted to be forced against said platform so as to position saidrota-table table thereon, a gun carrier mounted on said rotatable table comprising a tank adapted to contain Water, a series of curved barrels mounted in said. tank projecting therethrough and extending beyond the forward end thereof, said tank adapted at the rear of each of said curved barrels to receive the muzzle of a firearm in such a manner that the bore of the curved barrel will form a prolongation of the bore of the firearm.

2. In a device of the class described, a stationary platform, a rotatable table mounted thereon, upright standards carried by said table, a tank adapted to serve as a carrier pivoted on trunnions between said upright standards so as to tilt either way from the horizontal, an escapement and gear mechanism adapted to rotate said trunnions so as to tilt said carrier, means for locking said trunnions in any position to which they may be moved, means for locking said rotatable table to said platform at any position to which the same may be rotated, a series of curved barrels extending longitudinally through said" tank, the curved extremities thereof projecting beyond the forward end of said tank, the

rearward end of said tank provided with screwthreaded perforations in axial alinement with said curved barrels, each of said screwthreaded perforations adapted to receive the muzzle of a firearm in such a manner that the bore of the curved barrel will serve as a prolongation of the bore of said fire arm.

In testimony whereof, I sign this specification.

ALEXANDER T. FISCHER.
